Here is a Scripture that goes with the point you are making:
Thank you for your excellent discernment. The OT believers were baptized through the cloud and through the sea and they ate and drank of the same spiritual food that all do who believe in Jesus Christ. An amazing truth that Paul taught by inspiration of the Holy Spirit. We all are saved in the same way regardless of whether they looked forward or we look backward - it is by faith in the only Lord and Savior, Jesus Christ. God is so good!
